I think I first heard of the idea of eating cold ones when I read Bill Phillips' Underground Steroid Handbook - might be wrong, but I seem to recall he recommended those, and lots of Sustanon! 
I was OK with them, but for me, I ruined myself by eating water-packed Tuna straight from the tin - couldn't face the stuff for years... 
Fuck Bill Phillips........I taught him everything he knows.......
BUT I didn`t teach him everything that
I know.

FUCKING COPYCAT OF PEACE

As far as tuna goes Taff I ate so much of that shit it almost became akin to eating cat food.
I tried mixing everything you can think of to make it more palatable, but in the end,I would simply take a forkful and wash it down with water as if I was taking a pill.
For one contest I did, I bought 6 cases of tuna and ate it all during the prep.......it sux bigtime,but it`ll get you ripped as long as the rest of your diet is on point.
